Frequently asked questions
Does a furnace changeout need an inspection?
Yes in most jurisdictions. Combustion appliances are inspected for venting, combustion air and gas connections, and the permit is typically not closed until that inspection passes.
Is a high-efficiency furnace worth the extra cost?
It depends on how many heating hours the climate produces and the local fuel price. In cold climates the fuel saving usually repays the difference; in mild climates it often does not.
Do I need a permit for furnace replacement in North Dakota?
In most jurisdictions this work is permitted and inspected. Requirements are set locally, so confirm the current application and inspection checklist with your building department before work starts.
How long does furnace replacement take?
1 day of work, 1-3 weeks including permitting and inspection. Permit review and inspection scheduling are usually the largest source of variation.
What changes the price the most?
The largest cost drivers are input rating in btu and the efficiency tier selected; condensing (90%+) furnaces requiring new pvc venting and a condensate drain; gas line resizing or a new sediment trap and shutoff.
